An experiment was conducted to evaluate different Bacillus thuringiensis formulations for the management of podborers on pigeonpea for two years during 2010-11 and 2011-12 at Zonal Research Station, University of Agricultural Sciences, GKVK, Bangalore. Three formulations of Bt viz., Dipel, Halt and DOR were tested at 1.0 and 1.5 kg per ha and indoxacarb at 60 g a. i per ha was used as check. The results revealed that the lowest mean pod damage by Helicoverpa was recorded in indoxacarb with 19.94 per cent. Among Bt formulations, DOR Bt formulation at 1.5 kg per ha proved better by recording 28.89 per cent. The damage by podfly andfield infestation by bruchid was also of the same trend. Total pod damage was also in indoxacarb with 40.61followed by DOR Bt formulation at 1.5 kg per with 54.64 percent. Highest yield was recorded in indoxacarbtreatment with 1087 kg per ha followed by DOR Bt formulation with 895 kg per ha. The lowest yield was observed in untreated control with 599 kg per ha which was inferior to all other treatments.
